The Mercedes Vision EQXX study car consumes less than 10kWh per 100 kilometers – less than half the energy consumption of a luxury electric car of a similar size, or roughly equivalent to that of a Renault Twizy four-wheeled electric scooter.
The amazing result, which Mercedes says makes the EQXX the electrical equivalent of the iconic “one-liter car,” was achieved with a range of innovative solutions.
One of them is the terribly favorable medium resistance coefficient of only 0.17. That was the Cw value of Rudolf Caracciola’s record car, which ran the world road speed record (432.7 km / h) in 1938. This is achieved with a design that approaches the perfect drop shape, a retractable rear diffuser, special wheels and tires, a smoothed A-pillar and a number of other aerodynamic solutions.
It is also important to use the new generation of 900V batteries, which are 50% smaller and 30% lighter than the EQS battery pack of similar capacity (approx. 100 kWh) – important because it allows for a streamlined design and small, 1750 kilograms weight.
Due to its streamlined design and low weight, no extraordinary engine power was required: the EQXX can handle just 150 kW, or 204 horsepower. And this has contributed to the third pillar of economy, the amazing efficiency of the powertrain: it is more than 95% measured from the battery to the wheels, which is extremely favorable even among electric cars.
Consumption is also reduced by the solar panels that cover the roof: they are used for a number of auxiliary devices, but can even be used to charge the battery, which increases the range by 25 km (+ 2.5%) by 25 km. relieves the heating system.
Not only does the EQXX save the environment with its amazing economy: many components have been manufactured with a 3D printer to minimize waste. The back floor, for example, is a single massive cast aluminum that is not homogeneous, however: where no load-bearing elements are required, it contains only minimal material.
Most of the passenger compartment components are made from renewable and recycled materials. Vegan materials predominate, from mushroom yarns to cactus to bamboo fibers.
Such a special car deserves a special interface: the control is entrusted to artificial intelligence that simulates the functioning of the human brain, and instead of the traditional dashboard, an 8K resolution, 7680-pixel-wide, continuous display boasts. Both the AI and the monitor are energy efficient: they only consume power when and where it is really needed.
